爆破效果主要影响因素的灰色关联分析

Gray Correlative Analysis of Main Factors Affecting Blasting Effect

影响爆破效果的因素很多,灰色关联分析能确定出影响爆破效果各因素的主次关系。文中采用灰色关联分析方法,确定出某矿台阶深孔爆破效果的主要影响因素为底盘抵抗线、排距和炸药单耗,同时指出,在爆破设计中,适当调整孔网参数和炸药单耗,对控制爆破效果有重要作用。

There are many factors affecting blasting effect. The gray correlative analysis is able to determine the primary and secondary relations of various factors affecting blasting effect. The gray correlative analysis method is used to find out the main factors affecting deep--hole blasting effect of banks in a mine. The main factors are batholith resistance line, row spacing and explosive unit consumption. At the same time, it points out that properly adjusting hole network parameters and explosive unit consumption in the blasting design has an important effect in controlling the blasting effect.
